296.3.3 Sealing end at a building’s structureIf HVI®power Conductor are installed on a building’s structure, the calculated separation distance“s” in the sealing end range must be maintained from the metal parts in the building´s structure.The sealing end range ranges from the EB connection element to the connection of the earth connec-tion element (see Fig. 13).The mechanical contact with the EB element (semiconductive sheath) allows to discharge lightningimpulse voltages to a reference potential. To this end, a conductive connection to the next equipotentialbonding system (equipotential bonding level) of the installation is required.A UNI disconnecting clamp (Part No. 459 200, 200 kA) is used to connect the earth connection elementof the HVI®power Conductor to the earth-termination system.Figure 13 Sealing end range on a building’s structuredown conductorsealing end range35 cm -1800 mmsEBEB connection elementDetail A(Part No. 410 239)earth connection elementDetail BHVI ®power Conductorconnection to theearth-termination systemconnection to thebuilding´s equipoten-tial bonding systemDetail A:EB elementDetail B:connection of the earth connectionelementholder, e.g.Part No. 275 249disconnecting clamp,Part No. 459 200building’s structures
